Respiratory Muscle Training (RMT) works by effectively strengthening the respiratory muscles, (diaphragm, inter-costal muscles etc.), through breathing against a resistance. The Ultrabreathe is used to increase muscle strength, muscle power and stamina. Just like going to the gym and lifting weights.
The Ultrabreathe uses resistance to put load on the breathing muscles and has a wide adjustable range making it suitable to users of all fitness levels.
